ADDITIONAL INFO:
This bridge exhibits the more common design features of the County's stone bridges -- parapets with rounded top and horizontal curves at the portals.
This is one of the few bridges of this type which includes a tablet listing the people responsible for its construction. The stone tablet is mounted on the upstream wall facing traffic and more than half buried in dirt. The tablet extends lower than the name of the engineer, but would require more serious digging in a dangerous location.

After approximately one hundred years of service, the span appears to be in good shape. There are no weight limits and Glassport-Elizabeth Road is heavily traveled. But being so narrow -- 21 feet between stone parapets -- would seem to endanger the structure's future on a busy state road.
